Answer:

The measure of the angle labeled d

Step-by-step explanation:

I took the quick check for "angle angle side postulate"

Answer:

C

Step-by-step explanation:

It has to be either A or C because the function is decreasing as you move left to right, this only occurs when the number inside parenthesis is less than 1.

It isn't A because if you plug in x=0, the value is 2, but on the graph it is greater than 2.

Answer:

WY = 30

XZ = 10.5

Step-by-step explanation:

Paralellogram's diagonal's bisect eachother

Therefore,

[tex]n + 7 = 3 n[/tex]

Move the n over,

2n = 7

Divide both sides by 2,

n = 3.5

WY = 2(ZY) because definition of bisector

Simplify...

WY = 2(4n+1)

WY = 2(4(3.5)+1)

WY = 2(15)

WY = 30

You asked for XY, but the question asks for XZ, so I'm going to give XZ.

With n = 3.5 from above,

XZ = 3n

XZ = 3(3.5)

XZ = 10.5

The measure of XY and WY are; WY = 30 and XZ = 10.5

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

Since Paralellogram's diagonal's bisect each other

Therefore,

2n = 7

Divide both sides by 2;

n = 3.5

WY = 2(ZY)

because definition of bisector

Simplify;

WY = 2(4n+1)

WY = 2(4(3.5)+1)

WY = 2(15)

WY = 30

we asked for XY,

With n = 3.5 from above,

XZ = 3n

XZ = 3(3.5)

XZ = 10.5

The measure of XY and WY are; WY = 30 and XZ = 10.5

Answer:

Let's assume that Susan's graph is linear. Then, we can do linear interpolation. Let y be the amount charged for 10 hours of work done:

(7-10)/(7-11) = (168-y)/(168-264)

y = $240

For Jim's Lawn care, let's find the constant slope using points (1,20) and (2,40):

m = (20 - 40)/(1-2) = 20

Then, since the y-intercept is zero, the linear equation is:

y = 20x

Substituting x = 10 hours,

y = 20(10) = $200

The difference between the two would then be:

Difference = $240 - $200 = $40

Answer:

Proof below

Step-by-step explanation:

To prove DE and AB are parallel, we compare the slopes of both segments

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Segment AB goes through the points (0,0) and (x2,0), thus:

[tex]\displaystyle m_{AB}=\frac{0-0}{x_2-0}=0[/tex]

The slope is 0 because the line is horizontal.

Now for the segment DE, the endpoints are

[tex]\displaystyle (\frac{x_1}{2},\frac{y_1}{2}),\ (\frac{x_1+x_2}{2},\frac{y_1}{2})[/tex]

The slope is:

[tex]\displaystyle m_{DE}=\frac{\frac{y_1}{2}-\frac{y_1}{2}}{\frac{x_1+x_2}{2}-\frac{x_1}{2}}[/tex]

[tex]\displaystyle m_{DE}=\frac{0}{\frac{x_2}{2}}=0[/tex]

Segment DE is also horizontal, thus is parallel to segment AB.

Answer:

We conclude that the average number of pages that Sarah reads per hour will be: 10.75 page per hour

Step-by-step explanation:

Given

The average number of pages per hour can be calculated by simply dividing the total number of pages i.e. 64.5 pages by the number of hours spent on reading i.e. 6 hours.

Thus,

Average number of pages per hour = 64.5 pages / 6 hours

                                                            = 10.75 page per hour

Therefore, we conclude that the average number of pages that Sarah reads per hour will be: 10.75 page per hour

To find:

The value of [tex]\dfrac{dy}{dx}[/tex].

Solution:

We have,

[tex]y=\log_{\sqrt{x}}x[/tex]

It can be written as

[tex]y=\log_{\sqrt{x}}(\sqrt{x})^2[/tex]

Using property of log, we get

[tex]y=2[/tex]          [tex][\because \log_aa^x=x][/tex]

Now, differentiate both sides with respect to x.

[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(2)[/tex]

[tex]\dfrac{dy}{dx}=0[/tex]          [tex][\because \dfrac{d}{dx}(Constant)=0][/tex]

Therefore, the value of [tex]\dfrac{dy}{dx}[/tex] is 0.

Complete Question

Leicester City Fanstore (LCF) will be selling the "new season jersey" for the 2018-2019 season. The regular price of the jersey is $80. Each jersey costs $40. Leftover jerseys will be sold at the end of the season (or later) at $30. Since jerseys are produced in China and lead time is long, Puma wants LCF to decide the quantity right now (December 2017).

a. After some analysis using historic data, LCF expects that the demand will follow a Normal distribution with a mean 40,000 and a standard deviation of 8,000 due to uncertainty in team performance. How many jerseys should LCF order?

b. If a customer cannot buy the jersey from LCF (in the case of a stock-out), they may leave the store disappointed and use other channels (such as Puma stores or puma.com) in future. LCF thinks that the lost customer goodwill is around $10. Should LCF change their decision in part (a)? If yes, please state the number of jerseys LCF should order.

c. Please state whether the following statement is always true, and give a brief explanation. If [tex]C_o =C_i[/tex], the news vendor solution is the mean.

Answer:

a

   [tex]N = 46728[/tex]

b

  [tex]n = 47728[/tex]

c

  Yes it is always true  

Step-by-step explanation:

From the question we are told that

   The regular price of the jersey is  [tex]P_r = \$ 80[/tex]

    The cost of producing a jersey is [tex]C= \$ 40[/tex]

  The left-over price of the jersey is [tex]P_o = $ 30[/tex]

   The mean is  [tex]\mu = 40000[/tex]

   The standard deviation is [tex]\sigma = 8000[/tex]

   The cost of lost customer goodwill is [tex]C_g = \$ 10[/tex]

Generally the fund that LCF will loss for one jersey if they order for too many  jersey (i.e more than they need )is mathematically represented  

           [tex]C_o = P_o - C[/tex]

=>        [tex]C_o = 40 - 30[/tex]

=>        [tex]C_o = \$ 10[/tex]

Generally the fund that LCF will loss for one jersey if they order lesser amount  jersey (i.e less than they need )is mathematically represented  

           [tex]C_i = P_r - C[/tex]

=>        [tex]C_i = 80 - 40[/tex]

=>        [tex]C_i = \$ 40[/tex]

Generally the critical ratio is mathematically represented as

             [tex]Z = \frac{C_i }{ C_i + C_o}[/tex]

=>           [tex]Z = \frac{40}{ 40 + 10}[/tex]

=>           [tex]Z = 0.8[/tex]

Generally the critical value of  [tex]Z = 0.8[/tex] to the right of the normal curve is

         [tex]z = 0.841[/tex]

Generally the optimal quantity of jersey to order is mathematically represented as

             [tex]N = \mu * [z * \sigma][/tex]

=>          [tex]N = 40000 * [0.841 * 8000][/tex]

=>          [tex]N = 46728[/tex]

Considering question b

  Generally considering the factor of customer goodwill  the fund that LCF will loss for one jersey if they order lesser amount  jersey (i.e less than they need )is mathematically represented  as

           [tex]C_k = C_i + C_g[/tex]

=>        [tex]C_k = 40 + 10[/tex]

=>        [tex]C_k = \$ 50[/tex]

Now   the critical ratio is mathematically represented as

             [tex]Z = \frac{C_k }{ C_k + C_o}[/tex]

=>           [tex]Z = \frac{50}{ 50 + 10}[/tex]

=>           [tex]Z = 0.833[/tex]

Generally the critical value of  [tex]Z = 0.833[/tex] to the right of the normal curve is

         [tex]z = 0.966[/tex]

Generally the optimal quantity of jersey to order is mathematically represented as

             [tex]n = \mu * [z * \sigma][/tex]

=>          [tex]n = 40000 * [0.966 * 8000][/tex]

=>          [tex]n = 47728[/tex]

Considering question c

    When [tex]C_o =C_i[/tex] then

The critical ratio is mathematically represented as

             [tex]Z = \frac{C_k }{ C_k + C_k}[/tex]

=>           [tex]Z = \frac{1}{ 2}[/tex]

=>           [tex]Z = 0.5[/tex]          

Generally the critical value of  [tex]Z = 0.5[/tex] to the right of the normal curve is

         [tex]z = 0[/tex]

So

The optimal quantity of jersey to order is mathematically represented as

             [tex]n = \mu * [z * \sigma][/tex]

=>          [tex]n = 40000 * [0* 8000][/tex]

=>          [tex]n = 40000 = \mu[/tex]

Hence the statement in c is true

Answer:

the weekly sales are $8,800 to earn the similar amount with the two options

Step-by-step explanation:

The computation is shown below:

The earnings in option A is

= 40 hours × $22

= $880

Now let us assume the weekly sales be x

So the equation would be

10%x = $880

0.10x = $880

x = $8,800

Hence, the weekly sales are $8,800 to earn a similar amount with the two options

Answer:

48in sq

Step-by-step explanation:

8*12/2=8*6=48

Answer:

48in

Step-by-step explanation:

A triangle like this is like half of a rectangle. The rest fits in the upper left and right. So to find the area of the triangle, we're going to start be pretending it's a recrangle.

Our rectangle is 12 by 8.

12 x 8 = 96

If this were a rectangle, the area would be 96in.

Since it's a triangle and that's only half of a rectangle, the area is half of that.

96 / 2 = 48

The area of this triangle is 48in.

divide a binomial by a trinomial

Step-by-step explanation:

As we know that the polynomials are very closed to the addition, subtraction and the multiplication but the same cannot be happen under the division as the division of two polynomials could not become a polynomial it is not necessary

Now if we divide the binomial from a trinomial so it would give a rational expression and contain a negative exponent and negative exponent is not allowed under the same

Therefore the option B is correct
